I have a file as follows
it contains 3 text lines at starting, data with 2 columns for every 3 lines which have 5 columns in each line.
How to read it in matlab?
example:
# this is line 1
# this is line 2
#this is line 3

In particular, fopen() . fread() 3 lines and discard them. Then loop while ~feof()
cell2mat(textscan(fid, '%f%f', 1)) %to get the pair of numbers
cell2mat(textscan(fid, '%f%f%f%f%f', 3)) %to read the 5 columns
end of loop
each round storing the data somewhere appropriate
Though for your purposes, it might be easier to just loop using fscanf() as appropriate
